Three if you must know: 1. Has no links to it. 2. Not a seperate name the character is known by. 3. When typing "El Patrón" in the search box, it still comes up at the bottom of the search box despite the minor difference. (To clarify, I typed the entire name in the search box using a regular "o" and still saw El Patron at the bottom)
In short, I couldn't see a reason why it was still needed and since an admin deleted it I assume they agreed with my reasoning.
1. There was a link to the El Patrón page though.
2. The redirect makes it easier for people to access the page if they usually visit pages by typing in the URL instead of the search bar in within the wiki.
3. Same reason as pointer 2.
